Fortunately, the Republican's also lack a super majority in the Senate this time around.
Sorry, that is simply not true. Obamacare was passed without a single amendment (or even a full debate), and without a single Republican vote.
But my statement about the supermajority is true. The Democrats (with Independents) had at most 60 members of the Senate (2009-2010), Republicans had from 39-42 (vacancies and other things going on).
Democrats did not have sufficient control of the Senate to guarantee they could get whatever they wanted.
I recall one of the Republicans predicting that at some future time the Democrats were going to regret having used the nuclear option. That time is probably about right now.
I'm afraid there's no way to put that big cloud back into that shiny metal ball.
Democrats in the Senate used this super-majority to pass the ACA (Obamacare) in December 2009. Technically, they used the super-majority to end the filibuster and then voted on the bill.
Unfortunately, the Democrats have already gone nuclear repeatedly.
What makes you think the Republicans won't do the same?
EDIT: Ah, rules changes on filibuster and such. There's no guarantee. The Republicans do only have 51 members, though, with 48 for the Democrats and (per CNN's results) 1 seat still being tallied (?).
They could change the filibuster rules and make it easier on themselves, but it's a much narrower margin than in 2009.
EDIT 2: Regarding the empty seat, that's LA. If people vote in the runoff (not still being tallied) by the same party lines, it'll likely go to the remaining Republican candidate. So it'll be 52/48. Rule changes will need Democrats on board with them, this is unlikely.
There's a reason it was called the "nuclear option".
